AUTOMATIC RELEASING DEVICE ron onus Uron MINING-cactus.

Application filed January 21, 1915.

To all "1.071 cm it m (Ly concern Be it known that I, Snnarnvo GALLI, a subject of the King of Italy, residing at Mulberry, in the county of Crawford and State of Kansas, have invented certain new and useful Improvements in Automatic Releasing Devices for Cars upon Mining- Cages; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in automatic means for releasing cars from mining cages and consists of an apparatus especially adapted for use in connection with the car holding and releasing mechanism shown in my co-pending application Sr. No. 872,848.

The invention comprises various details of construction, combinations and arrange ments of parts, which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawing in which I have shown a side elevation of apparatus, part being shown in section. I

Reference now being had to the details of the drawing by letter, A designates a cage upon which the car is adapted to be held and B, B designate levers which are pivotally mounted upon the pins C, and each lever has a downwardly extending cam portion D adapted, as the lever B is tilted, to contact with a lever E which is pivotally mounted upon the pivot F, there being two sets of said levers similarly mounted upon opposite ends of the cage. A. spring Hbears against the under surface of the lever and tends to normally hold the same at its farthest upper throw and the inner end of the lever E bears against the block I which is adapted to be thrown up between the axles K of the truck or car upon the cage to hold the same from moving.

The present invention consists of the Specification of Letters Patent.

Serial No. 3,555.

means for automatically releasing said block and comprises a rod 0 which is pivotally piece 0 and through an aperture in a yoke J, which latter has forked arms 5 between which the pivotal pawl R- is mounted, having a hook R at one end. A lever T is pivotally mounted upon a pin T carried by the bracket arm T, which latter has a. re cessed portion T adapted to guide the yoke as it moves up and down. The end T of the pin T" is adapted to bear against the nose or projection It when the lever is tilted to the position shown in dotted lines, thus causing the yoke to be thrown down and with it the block I to the position shown in dotted lines and with the tilting of the lever the pawl R will assume the position shown in dotted lines. After the lever has tilted a suiiicient distance to allow the pawl to tilt to the position shown in dotted lines,

' the end of the lever will pass by the part B and a spring S, which is interposed between the block I and the bottom of a recess in the cross-piece 0 will return the block I to its normal position.

In operation, when the cage lowers to the bottom of the pit and the free end of the lever comes in contact with the bottom, the lever will draw down the block, releasing the truck and allowing the same to roll off the track. By the manipulation of the hand levers B, the same operation rnav be effected, althou h the hand levers form no part of the present invention asthey are contemplated in the application above referred to.

What I claim to be new is 1. An automatic releasing device for cars upon mining cages consisting of a frame to the cage, a spring-pressed pin engaging the yoke and pivotally connected to the block, a pivotal lever carried by the cage, and means upon the yoke engaged by said lever to cause the yoke to be drawn down having a block adapted to engage between the axles of a truck, a movable yoke secured to the cage, a spring-pressed pin engaging In testimony whereof I hereunto afiiX my the yoke and pivotally connected to the signature'in presence of two Witnesses. block, a pivotal lever carried by the cage, 7 -SERAFINO GALLI. and a pawl ,pivotally mounted upon the yoke 'Witnesses: 5 and having a projection in the path of the ARTHUR FULLER, end of the lever.
